International Law and Deportation of Enemy Aliens in Armed Conflicts

Enemy alien is used to refer to those aliens that are nationals of a country that you are fighting with. Theory and practice rightly distinguish between expulsion of alien in peace and war. A war will make nationals of your opposite state to enemy aliens. The belligerent state may consider it convenient to expel all of the aliens present in its country, including permanent or temporal residents. However this act may seem hard and unfair to aliens, but this has been accepted that this act is justifiable. International humanitarian law studies different situations including deportation or transfer of citizens such as aliens which are related to an armed conflict. However, states use this right largely by the excuse of internal security and public order. But the power of expulsion of aliens should be considered a special one and be used in special situations.
